[All MuleSoft Integration Architect I Questions]

An integration Mule application is deployed to a customer-hosted multi-node Mule 4 runtime duster. The Mule application uses a Listener operation of a JMS connector to receive incoming messages from a JMS queue.

How are the messages consumed by the Mule application?

ADepending on the JMS provider's configuration, either all messages are consumed by ONLY the primary cluster node or else ALL messages are consumed by ALL cluster nodes

BRegardless of the Listener operation configuration, all messages are consumed by ALL cluster nodes

CDepending on the Listener operation configuration, either all messages are consumed by ONLY the primary cluster node or else EACH message is consumed by ANY ONE cluster node

DRegardless of the Listener operation configuration, all messages are consumed by ONLY the primary cluster node

Show Suggested Answer

Suggested Answer: C

Correct answer is Depending on the Listener operation configuration, either all messages are consumed by ONLY the primary cluster node or else EACH message is consumed by ANY ONE cluster node

For applications running in clusters, you have to keep in mind the concept of primary node and how the connector will behave. When running in a cluster, the JMS listener default behavior will be to receive messages only in the primary node, no matter what kind of destination you are consuming from. In case of consuming messages from a Queue, you'll want to change this configuration to receive messages in all the nodes of the cluster, not just the primary.

This can be done with the primaryNodeOnly parameter:

<jms:listener config-ref='config' destination='${inputQueue}' primaryNodeOnly='false'/>

Option D? Really? Putting all the eggs in one basket doesn't sound like a good idea to me. I'll stick with C or B.

Yeah, I don't think putting all the load on one node is a good idea. Option C sounds like a more balanced approach.

I think option B might be the best choice here. It ensures all cluster nodes are consuming the messages.

I agree, option D does seem risky. I would go with option C just to be safe.

Haha, I bet the JMS provider is having a real fun time keeping up with this Mule application! Option A sounds like a wild ride.

I'm leaning towards option B. Seems like a safer bet to have all nodes consume the messages, just in case the primary node goes down or something.

User3: I'm not sure, but I think option A could also work depending on the JMS provider's configuration.

User1: I think option C makes more sense. Each message being consumed by any one cluster node sounds efficient.

That's interesting. I wonder how the Mule application handles message consumption in a multi-node cluster.

I believe all messages are consumed by ALL cluster nodes regardless of the Listener operation configuration.

Option C sounds like the way to go. It makes sense that the configuration would determine whether all nodes consume the messages or just the primary one.

Yes, it's important to consider the configuration settings to ensure the messages are consumed correctly by the cluster nodes.

I agree, option C seems logical. The Listener operation configuration should determine how the messages are consumed.

I think the messages are consumed by ONLY the primary cluster node based on the Listener operation configuration.
